Question

What is the range of the following function?

Answer 1

`[-5,5]`

Explanation:

The range is the y-axis, and the endpoints are filled in, so we put brackets.

Side note:

This is called Interval Notation. This is very important when you ask for the domain and range of functions (domain is for the x-axis). You will see this system A LOT, so you have to get used to the name and the language Interval notation uses.
